This setup is much more tractable than the general tensor network and allows us to understand phase transitions in the reflected entropy in detail. We will use the resolvent trick described in [1]} to compute the exact entanglement spectrum of \(\rho _{AA^*}\)  in the limit of large bond dimension. This allows us to compute the reflected entropy \(S_R(A:B)\) , along with other generalizations such as its Rényi versions, as a function of the bond dimensions. We will find a phase structure that is consistent with the holographic proposal [2]} for the reflected entropy at least away from phase transitions, and the spectrum will smoothly interpolate between the different phases.
